3.5 exe and 4.0 sources

[SzotsGabor]

3.5 does not work for me under Arena. I compiled it myself and it worked but it said it was 4.0. Would you mind clarifying this?

Hello! Sorry for the inconvenience, I forgot to change the version number. Done, I updated the release. It should work now.

Hi,

It displays 3.5 now but does not work either. And the sources are from January? 4.0 preceeded 3.5? Exe and sources do not match which is confusing.

EDIT: I can see now that compiling master I get 3.5.0 but compiling the source at 'Assets' I get 4.0.

Graham wanted me to send in Trinket. I never felt that Trinket was ready for another round, so I released it as V3.5 What do you mean by compiling the source at 'Assets?' I changed it to print v3.5.0, it should say v3.5.0 and work...

At this place: https://github.com/DkeRee/Trinket/releases/tag/V3.5.0 there is an exe and 2 source files. The date of the source files is 27 Jan. Compiling this source I obtain an exe which displays 4.0 as its version while the updated exe at the same place says it is v3.5.

Thanks for pointing that out to me. I have fixed it. Let me know if you encounter anything else. Thanks!

I am already running a gauntlet using my own compile of the master. It seems much stronger than the +300 you predicted.

Fantastic! Unexpected gains in elo like this is what I strive for when developing my engine. Though, I was hesitant to release V3.5 in the first place because, as I said, it's a little buggy. It crashes one out of around 20 thousand games and I simply have not had the time to figure out what is causing it. It randomly appeared at some point into development and I'm not sure exactly what is causing it. If you can print out error messages and send them my way it would be much help 😅

I've been rather busy with college applications this summer so I have not found the time to dig the problem out.

I can confirm that the 3.5.0 release version also does not work here, only tested from cmd. (Ryzen7 5700G)

To be more precise it opens up and displays correctly its info, but closes after giving the 'uci' command. Regrettably there is no error message and the event viewer log is not very helpful (quite generic), my gut feeling says the binary might have some hard coded path in it and it's trying to find some file.

No problem (except a few warnings) with compiling though and the compiled binary is working ok...

I can't think of anything that would cause it to break on a "UCI" command. There's no file it tries to fetch that I know of. I'm honestly at a loss with what's wrong.

[rwbc]

With what flags did you compile the release version? Did you by any chance compile it on an avx512 machine with march=native? The triggered error is the most generic (0xc000001d) one available in WIN.
